Effect of Pouring Temperature and Heating of Ceramic Shells Mould on Projection of Thin Wall Castings

One of the research directions this study is to determine possibility making precise, thin-walled castings from selected iron alloys. The scope work aimed at determining applicability casting process alloys with technology wax pattern, for precise a wall thickness less than 3 mm. article presents results tests carried out experimental shape steps, characterized by different thicknesses: 1 mm, 5 10 25 were made LH14, Gs42crMo4, L35H7MP2, LH26N9, 316L cast steel, and new alloy marked “0”. metal was smelted in an induction furnace capacity 150 kg. ceramic shell mould used plant make castings. Ceramic moulds heated chamber fixed temperature. time annealing constant form. following parameters variable during tests: alloy, pouring temperature, temperature mould.
